The highest value, of 14.017 mF/cm2 , was obtained for the electrode resulted by drop-casting a layer of 5,10,15,20-tetrakis(4-methoxy-phenyl)-porphyrin from benzonitrile on graphite support. Since a high double-layer capacitance value is characteristic of supercapacitors, out of the investigated samples, this electrode is the most likely to find application in their field. %Z Bibliogr.: 361. p. ; ill. ; összefoglalás angol nyelven
